AMSTERDAM — A division of Ahold USA has completed its acquisition of stores in the greater Philadelphia area.

Giant-Carlisle officially closed its acquisition of 15 Genuardi's stores, a subsidiary of Safeway. The deal was previously announced in January and was approved by the Federal Trade Commission last month.

As previously reported, during the conversion process, five stores at a time will temporarily close for about a week. The three-phase staggered approach is expected to be completed on July 22.
